China has admitted his arms manufacturers state met in July with representatives of Colonel Gaddafi and his forces fought against the rebels.
A spokeswoman said the meetings in Beijing took place without the knowledge of government.
She said no contracts were signed and delivered without arms.
The Security Council approved an arms embargo on Libya in February, the anti-Gaddafi protests pace gathered.
China's response followed a report Canadian newspaper said three state-owned enterprises of China had offered up to U.S. $ 200 million (£ 124m) in weapons to the Qaddafi sent during his visit July 16.
Citing documents found in the rubble on one side of the house of Tripoli, many former senior officials from Qaddafi, the Toronto-based Globe and Mail said the weapons offered include anti-tank missiles and rocket launchers.
The documents, said shipping companies suggested the arms through Algeria and South Africa, but would not confirm if all the military assistance was delivered, the newspaper said.
"Treat it seriously"
Chinese Foreign Ministry Spokeswoman Jiang Yu told a daily briefing that the weapons had been sent.
"Gaddafi's government sent people to China without the knowledge of the Chinese government and engaged in contact with a handful of people in the companies concerned," he said.
"Chinese companies have signed arms contracts and trade or otherwise export military goods to Libya."
The national organizations dealing with arms trafficking "without doubt this seriously," he said.
The income will complicate China's relationship with the Libyan regime of entry, says the BBC's Damian Grammaticas in Beijing.
China has not recognized the rebels as the new government of Libya and the admission of new seems to confirm that while the rule Gaddafi was coming to an end, China continued to protect their bets.
In June China had the rebel leadership of Libya in Beijing, as they sought to establish contact with them. It is now clear that only a few weeks later the men Gaddafi were looking for weapons in China.
The new leaders of Libya can be hard to believe that China did not know that the Libyan authorities in the country trying to get a large order of arms from China's state-controlled companies, our correspondent says.
And there have been suggestions that China's lack of support for the rebels can mean to their companies lose in future agreements for the supply of oil from Libya sought.
